に支持することを特徴とするレーザー記録装置。 A laser light source modulated by an image signal, a deflector that deflects the laser beam emitted from the laser light source, a lens group that focuses the laser beam scanned by the deflector, and guides the laser beam onto the photoreceptor. In an image forming apparatus that includes an optical scanning device having a reflective member and transfers and records an image formed on a photoconductor by the optical scanning device onto a conveyed transfer paper, the optical scanning device transfers the image to a main body including the photoconductor. The optical scanning device is supported on the main body by a fixed part that determines the position of one point in the paper transport direction, and a support part that supports the optical scanning device slidably in the transfer paper transport direction with respect to the main body at at least one other place. A laser recording device featuring:
